Today I purchased a package of GoodNites Disposable Bed Mats. I used one this afternoon during my Sunday Afternoon Nap Time. Compared to the Walmart "ASSURANCE" brand XL-Size Disposable Under-Pads, the GoodNites Disposable Bed Mats seem to be sturdier and more absorbent. Being Autistic and having Cerebral Palsy and being totally incontinent, absorbency is very important to me, since I am flat on my back for hours and hours between my side-safety rails in my bed at nap time and at bed time. A good feature of these GoodNites Disposable Bed Mats, is the 4-point adhesive pads to secure the Disposable Bed Mat to my bed sheet. The bed mat "does not slip", which is better than the ordinary 30" x 36" disposable bed pad. Although a little bit smaller, the GoodNights Disposable Bed Mats are a better product to keep my bed dry, even though I am heavily diapered and wearing plastic pants over my diaper(s).
